7200 X 8 =57600. To achieve a sampling frequency of 7200 Hz a sample has to be taken every 14.745Mhz/7200 = ~2048 cycles.To get one A/D conversion result each 2048 clock. cycles a conversion will be ready after 13 * 128 = 1664 cycles. i had to fill with 2048 -1664.

Generally, when "running out of" timers, simple software routines based on timer interrupts will take you pretty far. For example, using one of the timer compare interrupts you could easily generate almost all frequencies: In the timer compare ISR just toggle the respective output pin and (let the timer be) reset to 0.
